Abstract: A method of preserving porcine heart valves (16) so that they may be incorporated into prosthetic heart valves for human implant. During fixation, the leaflets of the valves are repeatedly flexed throughout their full range of motion. Flexing of the leaflets continues throughout fixation, and is accomplished by providing for alternating fluid flow through the valve from the inflow and outflow sides sufficient to cause the leaflets to fully open and close.

Abstract: A varactor tuned oscillator (10), VCO, operational in the millimeter wave range including frequencies greater than 30 GHz, includes a lumped element active circuit (12) with a negative resistance, a lumped element tuning circuit (16) coupled to the active circuit and providing resonant circuitry in combination therewith, and a VCO output (26) reactively terminated at the fundamental frequency of oscillation and generating a higher order output harmonic at least as high as the second order. The reactive termination at fundamental frequency eliminates the intrinsic diminishing effect on tuning range of resistive loading, to extend tuning range and provide an ultrabroadband VCO. The VCO output (26) is resistively loaded at the higher order harmonic. The output is obtained from the higher order harmonic generated in-­situ in the active element (14). Measured performance includes continuous tuning from 46 to 66 GHz, a 20 GHz tuning range, with a maximum power output of +6 dBm.

Abstract: Laser beam L is scattered by particles in the sample cell 1. Photosensor assembly 33 detects forward scattered light and assembly 5 detects sideward and backward scattered light for the purpose of increasing the precision of measurement. Both the photosensor assemblies are temperature-monitored by sensors 6 and 7 to prevent erroneous measurement due to small temperature-dependent zero-level shifts of photosensors used in the photosensor assemblies. If temperature variations of or a temperature difference between the assemblies exceeds a predetermined value, an alarm signal is generated with the measurement interrupted automatically.

Abstract: In a communication system such as a telephone system and an electronic mail system with language translating function, wherein between a terminal (1) of a first language and a terminal (2) of a second language, sentences inputted from the first-language terminal are translated into the second-language and the translated sentences are outputted to the second-language terminal words appearing in sentences inputted from the second-language terminal are memorized so that the memorized words are preferentially selected when determining equivalents in later translation of sentences inputted from a first-language terminal. In a type of communication system in which translation is achieved in bi-directional manner between the terminals, words appearing in sentences inputted from the first-language terminal are also memorized so that the memorized words are preferentially selected when determining equivalents in later translation of sentences inputted from the second-language terminal. As means for memorizing an occurring word, a sentence number assigned to an input sentence containing the word may be stored in a word dictionary as activation degree information of the word or an occurring word file (115, 215) may be disposed for sequentially storing therein the occurring word. These items may be stored in combination with terminal user IDs. Various types of function allocation method are possible such as a type wherein input sentence is analyzed by an input terminal so as to send the analyzed information to a destination terminal, which then generates a translated sentence from the received information and a type wherein a translated sentence obtained by a terminal of an input side is sent to a terminal of a destination side.

Abstract: Higher harmonic power components (P h , Q h ) and fundamental wave reactive power components (Q o ) are derived from a load voltage (V S ) and current (i L ), using theory (instantaneous p-q theory) regarding instantaneous real power and instantaneous imaginary power. Gains are then obtained which make the higher harmonic power components (P h , Q h ) and fundamental wave reactive power components (Q o ) not exceed predetermined limit values. The higher harmonic power components (P h , Q h ) and fundamental wave reactive power components (Q o ) are respectively multiplied by the gains to obtain limited higher harmonic power components (P h ', Q h ') and fundamental wave reactive power components (Q o '). An output current command is generated in accordance with the limited higher harmonic power components (P h ', Q h ') and fundamental wave reactive power components (Q o '). The output current command is supplied to an inverter which in turn supplies a compensation current (i c ) to the power system.

Abstract: A window panel regulating and sealing assembly, particularly suited for use in combination with a vehicle door, for raising and lowering a window and assuring a perfectly flush and fully sealed condition at the vehicle exterior. The window is supported at its front and rear sides within vertically disposed guide channels by means of pivotal sliding type upper guide members attached to the window approximately at midpoint thereof and by means of lower guide members attached to the window at the lower edge thereof. The guide channels include an outwardly extending, abruptly curved ramp section within which the lower guide members track and cause the window to pivot about the upper guide members as the window is at its near uppermost raised position thereby causing the window at its upper and lower extremities to firmly bear against respective relatively non-yielding sealing members to establish a perfectly flush positioning of the window relative to the vehicle exterior. The guide channel members between the upper and lower guide members include an adjacent sealing housing with a vertically disposed U-shaped elastomeric sealing member disposed therewithin and with its open end facing the window and receiving in sealing engagement a vertically disposed vane type sealing member affixed to the window and extending from the upper guide member to the lower guide member whereby a seal is maintained between each guide channel and the window between the upper and lower guide members at all times during the raising and lowering of the window during which the upper guide member is above the beltline as the window is being raised or lowered and when the window is in the fully raised position.

Abstract: The invention comprises method and apparatus for time-multiplexing a resource (MR) among entities which require access to the resource at a rate which is controlled over both an averaging interval and a jitter averaging interval which is shorter than the averaging interval. The technique employs a set of frame queues (117) of work descriptors (103) representing the work to be done by the resource for the entities. Each frame queue is associated with a frame of rime slots in which the resource performs work. A resource server (121) provides work descriptors from the head of a given frame queue for the frame associated with the frame queue and then serves the next frame queue for its frame. A queue manager (107) places work descriptors received from the entities at the tails of the frame queues. The work descriptors from a given one of the entities are placed in the frame queues in such fashion that when the resource server takes work descriptors from the heads of the frame queues, it automatically provides the work descriptors for a given entity to the resource at the required controlled rate. The resource server may serve one or more best effort queues (115) in addition to the frame queues. The work descriptors (103) in the best effort queues represent work for entities which do not required a controlled rate of access. The resource server serves a best effort queue when a frame queue is empty but there are time slots remaining in its frame.
